  • Publication number: 20140168635
    Abstract: An inspection method and an inspection fixture for the scribing lines of a wafer are disclosed. The inspection method includes the following steps: providing a wafer having multiple chips and a lower surface attached with a dicing tape, wherein scribing lines are formed between the chips; connecting the dicing tape with a transparent carrier supporting a first liquid medium such that the dicing tape is contacted seamlessly with the first liquid medium, wherein the difference of refractive index between the first liquid medium and the dicing tape is less than 0.3; and inspecting the scribing lines through the transparent carrier from below the lower surface of the wafer by an inspection lens of an optical inspector. The inspection method and fixture increase the image resolution of the scribing lines so as to facilitate the detection of lower-surface defects of the scribing lines.

  • Patent number: 7063246
    Abstract: A brittle material rotating and aligning mechanism including a bearing, a rotary table, and a driving mechanismU, and installed in the worktable of a brittle material scribing and breaking apparatus; carries brittle material, for example, a semiconductor wafer for scribing and breaking into individual dies. The driving mechanism uses a flexible transmission member to rotate the rotary table for low installation cost, no requirement for a precision adjustment during installation, and, preventing the occurrence of back lash or the production of particles due to friction between the transmission member and the driving wheel of the driving mechanism, or between the transmission member and the rotary table.

  • Patent number: 6932259
    Abstract: A brittle material breaking apparatus using a lifting mechanism to lift/lower a carrier wherein the lifting mechanism is controlled to lift the carrier for holding the brittle material for breaking, and then to lower the carrier from the brittle material to a distance for enabling the brittle material to be shifted to a next scribe line for further breaking, preventing the occurrence of friction between the brittle material and the carrier and the production of static electricity and micro particles and, improving the breaking quality. The brittle material breaking apparatus further includes a stroke fine adjustment mechanism adapted to adjust the stroke of the breaking-cutter relative to the brittle material.

  • Patent number: 6896470
    Abstract: The invention includes mainly a machine base, a carrier, a sliding control mechanism, a latch mechanism, a horizontal shifting mechanism, and a lifting mechanism. The FOUP (front-opening unified pod) is put on the carrier and latched by a locking plate of the latch at an accurate position. The carrier moves forwardly to tightly engage the FOUP to a gate on an access at a backboard of the machine base, and thus a cover of the FOUP is opened by a headstock gear at the back of the gate then carried backwardly away from the FOUP by the horizontal shifting mechanism and lowered by the lifting mechanism. Reversely, the cover is closed on the FOUP. As such, the cover is loaded and opened automatically, as well as in closed, which can be a part of automation and prevents wafers from contamination.
